Automated reading of historical handwriting is needed to search and browse ancient manuscripts in digital libraries based on their textual content. In this paper, we present a combined system for text localization and transcription in page images. It includes flexible learning-based methods for layout analysis and handwriting recognition, which were developed in the context of the Swiss research project...
This paper presents a comparison between three classifiers based on Support Vector Machines, Multi-Layer Perceptrons and Gaussian Mixture Models respectively to detect physical structure of historical documents. Each classifier segments a scaled image of historical document into four classes, i.e., areas of periphery, background, text and decoration. We evaluate them on three data sets of historical...
This paper proposes a novel text line extraction method for historical documents. The method works in two steps. In the first step, layout analysis is performed to recognize the physical structure of a given document using a classification technique, more precisely the pixels of a coloured document image are classified into five classes: text-block, core-text-line, decoration, background, and periphery...
Trans-radially amputated persons who own a my-olectric prosthesis have currently some control via surface elec-tromyography (sEMG). However, the control systems are still limited (as they include very few movements) and not always natural (as the subject has to learn to associate movements of the muscles with the movements of the prosthesis). The Ninapro project tries helping the scientific community...
This paper describes a generic layout analysis system for historical documents. It presents the architecture of a pyramidal approach using three analysis levels. Each level consists of a classifier using machine learning techniques where the output of the upper level is used as a feature in the lower level. The current implementation uses a so called Dynamic Multi-Layer perceptron (DMLP), which is...
Medieval manuscript layouts are quite complex. They contain textual elements such as insertions, annotations, and corrections. They may be richly decorated with ornaments, illustrations, and decorative initials making their layout even more complex. In this paper we describe a semi-automatic tool which annotates medieval manuscripts using our generic format. This format allows to represent the physical...
